TYPOGRAPHICAL COMPOSING-MACHINE.

Specification of Letters Patent.

Patented Oct. 27, 1914.

7 '0 a? Z whom it may concern Be it known that I, CARL MUEHLEISEN, a citizen of the United States of America, residing at 23 Chausseestrasse, Berlin, N. 4, in the Empire of Germany, have invented new and useful Improvements in Typographical ComposingMachines, of w 1ch the following is a specification.

The invention relates to typographical composing machines such as those known commercially under the trade mark Linotype and particularly to those machines which have a plurality of super osed magazines which are vertically mova le as a single entity for the purpose of bringing them successively into working position, and the invention consists in improved means for effecting the said vertical movement. The devices according to the present invention, differ from known constructions for the same urpose, in respect of the fact that for the raising of the said magazines, only a s ngle cam disk is used, upon which cam disk the magazines are supported atthree or more parts. These means are, in themselves, of simple construction, and they provide for a quick and uniform adjustment of the magazines, there being practically but one moving organ so that p ay between several moving parts is avoided.

The drawing shows, more or less d1a rammatically, a constructional form of t e invention, Figure 1 being a side elevation of the machine, and Fig. 2 a plan of the magazines.

In the example illustrated, two ma azines (2%, resting upon the magazine frame 3. The magazine frame 3, is prevented, by a guide rod 4, from moving in any direction other than that perpendicular to its inclined magazinesupporting surface, and it carrles on 1ts underside, three supporting rollers 5; or, 1f desired, there may be four such rollers. These rollers 5 bear upon the cam disk 6 which is free to rotate about a stationary inclined shaft 7 fastin a bracket 8. The cam disk 6 is formed with as many humps or projections 9 as there are rollers 5 wlth which they are caused to engage when the disk 6 is rotated, this engagement causing the magazines to be moved in the direction of the axis of the shaft 7 The cam disk 6 is provided with a handle 10 to enable it to be readily turned for raising or lowering the magazines.

In machines provided with more than two magazines, each of the cam-projections 9 is formed with steps each corresponding with a different position to be assumed by the column of magazines.

Having described my invention, I declare that what I claim and desire to secure by Letters Patent is:

1. In a typographical composing machine the combination with a plurality of superposed magazines movable as a whole for ringing the different magazines successively into operative position, and a magazine frame supporting the said magazines, of a cam disk beneath the magazine frame and rotatable about an axis intersecting said frame, and rollers on the said frame, bearing on the cam disk.

2. In a typographical composing machine, the combination with a plurality of superposed magazines movable as a whole for bringing the different magazines successively into operative position, and a magazine frame su porting the said magazine, of a cam disk eneath the magazine frame, rollers on the said frame, bearing on the cam disk, and stepped projections on the cam one for each roller on the magazine frame.

3. In a typographical machine, the combination of a plurality of magazines, and a circular cam-shaped disk for shifting the magazines to bring one or another into operative position, said disk being rotatable about an axis intersecting the magazines.

4. In a typographical machine, the combination of a plurality of magazines and a rotary'cam for shifting the magazines to bring one or another into operative position, the said cam being rotatable about an axis intersecting the magazines.

5. In a typographical machine, the combination of a p urality of magazines, and a circular cam-shaped disk, rotatable about an In witness whereof I have hereunto set my axis intersecting the magazines, for shifting hand in the presence of two witnesses.
